HAND-PUMP FOE EXIRACTING KEROSEN E OR OTHER- LIQUIDS FROM IiNS.

SPECIFICATION forming part of Letters Patent No. 618,728, dated January31, 1899.

Application filed July 3, 1897. Serial No. 643,4l2. (No model.)

To all whom it may concern;

Be it known that I, WILLIAM JOHN RAW- LING, tinWare-man ufaeturer, asubject of the Queen of Great Britain and Ireland, and a resident ofPulteney street, Adelaide, South Australia, have invented a certain newand useful Improved Hand-Pump for Extracting Kerosene or other Liquidsfrom Tins, of which the following is a specification.

This invention is for the purpose of providing a small hand-pump whichshall be simple and economical'in construction and at the same timecontain within itself the means of piercing a tin, such as akerosenetin, without removing it from its wooden case for the insertionof the pump, and means for retaining the pump and its outlet-spout in afixed position and for practically preventing drip from the outlet.

I am aware that heretofore devices have been employed for securing apump, including a clamp passing to and under the bottom of the tin andsecured to the pump-barrel, or by wire guys from the head of the pumpwhich are forced into the top of the tin in several places.

By my pump a tin may be pierced and with one hand be pumped emptywithout removing the tin from its wooden case and without causing wasteor drip from the spout, while the other hand of the operator is leftfree to hold a receptacle, such as a lamp, under the spout.

According to my invention the retention of the pump and its outlet-spoutin the required fixed position is secured bya screw or screwingarrangement attached in convenient form to the waist of the pump andadapted to fit upon or into the top of the tin. A suitable hole forinserting the pump-barrel and en gaging the screw is formed in the tinby using a spike attached at right angles to the barrel of the pump.

In order to enable the piston of the pump to be easily provided andrenewed when required and the last contents of the tin to be removed, Ihave devised a simple piston-head, preferably of leather, fitted in themanner hereinafter described, and a suitable inlet chamber and valve atthe bottom of the barrel.

In the drawings, Figure 1 is a view of my pump complete in position in akerosene-tin. Fi s. 2 and 3 are enlar ed views of the istonhead, theformer showing its position during v the downstroke and the latterduring the upstroke. Fig. 4 is an enlarged view of the chamber and valveat the bottom of the barrel, which enables the last contents of the tinto be exhausted. Fig. 5 is an enlarged view of the piercing-spike whichis affixed to the pump-barrel. Fig. 6 is an enlarged View of thefastening arrangement which after the tin has been pierced by thepiercer attaches and holds the pump to the tin. Figs. 7, S, and 9 areenlarged views of modified constructions for holding the pum p-barrelonthe tin or can.

The pump-barrel A'is formed of tin or other suitable material of thenecessary length and size and provided with a spout B, preferably of theshape shown, which allows the kerosene to run back into the barrel A andprevents drip when the pump ceases to be operated. The valve andvalve-chamber in the bottom of the pump-barrel comprise an annular pieceof wood or other suitable material O, to which is attached a flap ofleather D. The piston-head consists of a flat disk of leather E, with ahole in the center, which forms an annular aperture around the pistonrodF. The head E during the upstroke of the pump rests upon a metal disk IIon the end of the rod F, which closes the central aperture, as shown inFig. 3; but during the downstroke the head E is held by a wire ring J,which leaves an annular space around the rod corresponding with the onein the head E, as shown in Fig. 2. The upper end of the piston-rodpasses througha cap G, whichfits into the top of the barrel A. To thetop of the barrel is soldered or otherwise rigidly, secured a spike Kfor piercing the tin to admit the insertion of the pump-barrel. Thisspike consists, essentially, of a metal cone tapering from a sharp pointto a size equal to the diameter of the pump-barrel. It may have a plainsurface or it may be provided with one or more wings, (one of which, K,is shown in Fig. 1,) according to the style of the fastening to be used.The screw or screwing arrangement I prefer is that shown in Figs. 1 and6, which consists of a shoulder L immediately above a screw-thread M,rigidly secured to the pump-barrel, said screwthread being spaced fromthe shoulder sufficiently to allow the top of the tin to be clampedbetween the shoulder and the screwthread.

In operation the pump is held horizontally and the piercer pressed bythe hand through the capsule many other part of the top of the tin to beemptied, forming a hole, into which the pump-barrel is then inserted.The hole made by the piercer having a wing K provides a radial slitwhich allows the screwthread to enter easily. A turn is then given andthe pump and spout are thus held securely in the desired position.

Fig. 7 illustrates a fastening device consisting of the ordinary metalcap N used on kerosene-tins, fitted upon the pump-barrel A between twoflanges L fixed to the pump-barrel, so that when the pump is placed inposition the lower flange is securely held between the tin and the cap.In this case the spike K will be a plain one, as shown in Fig. 5.

In Fig. 8 the screw arrangement is formed of projections P, attached tothe pump-barrelunder the flange L. In this case the piercer K willrequire to have two,three,or more wings like K to correspond with theprojections on the pump-barrel. The projections P on the barrel havingbeen inserted through the slits in the tin a partial turn is given tothe pump, and the tops of the projections by the screw action hold thepump tightly to the top of the tin.

Fig. 9 represents a similar arrangement; but in this case the piercer Kwill require to have two wings K to correspond with the two projectionsP on the pump-barrel. After the pump has been inserted and given ahalf-turn the nut R is screwed down tight.

I would have it understood that I do not limit myself to the detailsherein set forth. The shape of the screw attachments may he modified inmany ways without departing from the spirit of my invention.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. A pump having apointed piercer attached thereto atright angles to the barrel, a screwing device adapted to fit upon orinto the top of the tin, a shoulder immediately adjacent to suchscrewing device, a piston-head consisting of a fiat disk with an annularaperture around the piston-rod, its upward movement governed by a metaldisk rigidly attached to the bottom of the rod and its downward movementgoverned by a wire ring substantially as described and for the purposesset forth.

2. A piercer consisting of a conical body provided with a longitudinalwing projecting therefrom, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname, in the presence of two witnesses, this 18th day of May, 1897.

WILLIAM JOHN RAlVLING.
